      99.1           February 2004 Monthly Operating Report of Trenwick
                     America Corporation, dated March 22, 2004.

      99.2           List of non-Debtor entities

Item 9. Regulation FD Disclosure

A. On March 22, 2004, Trenwick America Corporation (the "Company" or the
"Debtor") filed a monthly operating report as of August 20, 2003 and February
29, 2004 and for the month ended February 29, 2004 and the period from August
20, 2003 to February 29, 2004 (the "February 2004 Monthly Operating Report")
with the United States Bankruptcy Court for the District of Delaware (the
"Bankruptcy Court"). A copy of the February 2004 Monthly Operating Report is
attached hereto as Exhibit 99.1, and is incorporated herein by reference. The
February 2004 Monthly Operating Report includes financial information only with
respect to the Company. Accordingly, the Operating Report does not contain
detailed financial information with respect to those subsidiaries and affiliates
of the Company that have not commenced proceedings to reorganize under chapter
11 of the United States Bankruptcy Code. The non-Debtor entities are listed in
Exhibit 99.2.

      The February 2004 Monthly Operating Report (the "Operating Report") is in
a format prescribed by the applicable bankruptcy laws. Readers are cautioned not
to place undue reliance upon the information contained in the Operating Report.
The information in the Operating Report has been prepared in accordance with
accounting standards generally accepted in the United States of America for
interim reporting, with the exception of accounting for wholly-owned
subsidiaries of the Debtor, which have not been consolidated. In addition,
certain information and footnote disclosures required by accounting principles
generally accepted in the United States of America have been condensed or
omitted for purposes of the Operating Report. There can be no assurance that the
Operating Report is complete, and the Company undertakes no obligation to update
or revise the Operating Report. The Operating Report has not been audited or
reviewed by independent accountants.

      The unaudited information in the Operating Report is subject to further
review and potential adjustments and is not necessarily indicative of future
results. In addition, the Operating Report contains information for periods
which are different from those contained in the Company's reports pursuant to
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and does
not include consolidated results of the Company. Accordingly, the substance and
format of the Operating Report does not allow for meaningful comparison with the
Company's previously disclosed consolidated financial statements.



      Although not included in Exhibit 99.2 hereto, the February 2004 Monthly
Operating Report of Trenwick America Corporation as filed with the Bankruptcy
Court also included Federal tax returns. The financial statements included in
the Operating Report were prepared using certain assumptions and estimates that
are subject to revision. Any adjustments for these estimates (based upon changes
in facts and circumstances, further analysis, and other factors) will be
reflected in the financial statements in the period during which such
adjustments are made. These adjustments could have a material impact on reported
results in the future.

      In the future, so long as the Company remains under the supervision of the
Bankruptcy Court, in lieu of filing quarterly reports on Form 10-Q and annual
reports on Form 10-K, the Company intends to file on Form 8-K its monthly
operating reports as filed with, and in the format prescribed by, the Bankruptcy
Court.

      The Company is a debtor and debtor-in-possession in In re Trenwick America
Corporation, et al., Case No. 03-12635 (MFW) (Bankr. D. Del. 2003).

Limitation on Incorporation by Reference

      In accordance with general instruction B.2 of Form 8-K, the Operating
Report and other information in this Report (including exhibits) are furnished
pursuant to Item 9 and shall not be deemed to be "filed" for the purposes of
Section 18 of the Exchange Act, or otherwise subject to liabilities under that
Section, nor shall they be deemed to be incorporated by reference in any filing
under the Securities Act of 1933, as amended, except as expressly set forth in
such filing. This report will not be deemed an admission as to the materiality
of any information in the report that is required to be disclosed solely by
Regulation FD.

      Pursuant to the requirements of the Securities Exchange Act of 1934, the
